During field artillery fire-mission preparations, battery personnel must monitor the temperature of modular artillery charge systems (MACS). Propellant charges stored in external ammunition readiness racks must be stabilized between 60°F and 70°F before loading. If ambient exposure causes propellant temperature to drop below 40°F, crews are required to record the exact casing surface temperature in the computerized fire direction system (FDS) rather than attempting rapid artificial heating. Artificial heating can degrade the nitrocellulose binder and cause erratic chamber pressures. Once registered in the FDS, ballistic software automatically recalculates muzzle velocity deviations to adjust the gun's quadrant elevation.

According to the passage, what specific action must artillery crews take if propellant charge temperatures drop below 40°F?

  1. A
    Apply rapid artificial heating to raise the propellant back to standard temperature.
  2. Record the exact casing surface temperature in the computerized fire direction system.Cevap
  3. C
    Manually recalculate ballistic muzzle velocity deviations prior to gun elevation.
  4. D
    Return the cooled propellant modules to external readiness racks for thermal stabilization.

Cevap

Record the exact casing surface temperature in the computerized fire direction system.
The author explicitly states that when propellant temperature drops below 40°F, personnel must record the exact casing surface temperature in the computerized fire direction system (FDS).

Adım Adım Çözüm

1
Scan the passage for the specific condition highlighted in the stem.
Identified the condition: 'propellant temperature to drop below 40°F'.
Direct fact retrieval requires locating the exact operational trigger stated in the text.
2
Extract the mandatory procedural requirement linked directly to this trigger.
Located the direct statement: 'crews are required to record the exact casing surface temperature in the computerized fire direction system (FDS)'.
The question asks for the required action mandated by protocol under that precise temperature condition.
